Answer: A= -5
Step-by-step explanation:
Asking the Math Gods...
A=W*L
9*3=27in^2
9*5=45in^2
Let A be the event 
and B be the vent

, the events A and B are mutually exclusive.
The number is either odd or even. Since 
, the events are mutually exclusive and exhaustive.
Correct choice is "the number is either odd or even".
